The wonderful Matilija Poppies, Romneya coulteri, are in full bloom in the East Bay hills across the water from San Francisco, California. White, platter-sized translucent flowers dominate a tall stem on a bush-like construction, with an intricate yellow central flower core. The Matilija is a genuine native of the southwest United States and California, and grows like a weed. Shown here with Echinacea and Clematis from our garden (the blue Clematis is hidden behind the more frontal Matilija).
